AI Article Synopsis
- Histone deacetylases (HDACs) are important in cancer development, leading researchers to focus on HDAC inhibitors (HDIs) as potential cancer treatments.
- While some synthetic HDIs are available, they often have major side effects, prompting interest in natural alternatives, particularly those derived from Morinda lucida Benth.
- The study assessed the binding ability of various compounds from Morinda lucida to HDACs, finding that several phytosterols and triterpenes showed higher HDAC inhibitory activity than a known synthetic inhibitor, making them promising candidates for cancer therapies.
Article Abstract
The important role of histone deacetylases (HDACs) in the development of cancer has been demonstrated by various studies. Thus targeting HDACs with inhibitors is a major focus in anticancer drug research. Although few synthetic HDAC inhibitors (HDIs) have been approved for cancer treatment, they have significant undesirable side effects. Therefore emphases have been placed on natural HDIs as substitutes for the synthetic ones. In a bid to identify more HDIs, this study evaluated the binding tendency of compounds derived from Morinda lucida Benth. towards selected HDACs for the discovery of potent HDIs as potential candidates for anticancer therapeutics, based on the report of anticancer potentials of Morinda lucida-derived extracts and compounds. Givinostat and 49 Morinda-lucida derived compounds were docked against selected HDAC isoforms using AutodockVina, while binding interactions were viewed with Discovery Studio Visualizer, BIOVIA, 2016. Druglikeness and Absorption-Distribution-Metabolism-Excretion (ADME) parameters of the top 7 compounds were evaluated using the Swiss online ADME web tool. The results revealed that out of the 49 compounds, 3 phytosterols (campesterol, cycloartenol, and stigmasterol) and 2 triterpenes (oleanolic acid and ursolic acid) exhibited high HDAC inhibitory activity compared to givinostat. These 5 compounds also fulfill oral drugability of Lipinski rule of five. Morinda lucida-derived phytosterols and triterpenes show high binding tendency towards the selected HDACs and exhibited good drugability characteristics and are therefore good candidates for further studies in the search for therapies against abnormalities linked with over-activity of HDACs.

Benzo[a]pyrene (B[a]P) is a hazardous polycyclic aromatic hydrocarbon that accumulates in several environmental matrices as a result of incomplete combustion. Its presence, carcinogenic properties, and tendency for bioaccumulation provide significant risks to human health and the environment. The objective of this study is to create an immunoassay for the detection of benzo[a]pyrene utilizing immunoglobulin Y antibodies.

Up to 50% of individuals with uveal melanoma (UM), a frequent cancer of the eye, pass away from metastases. One of the major challenges in treating UM is the role of receptor tyrosine kinases (RTKs), which mediate the epithelial-mesenchymal transition (EMT) of tumors. RTKs are involved in binding multiple growth factors, leading to angiogenesis and vasculogenic mimicry (VM) phenomena.

The present study investigated the covalent binding behavior of the flavonoids, catechin, eriodictyol, luteolin and quercetin with β-lactoglobulin (βlg). Since the four flavonoids possess the identical A- and B-ring structures, effects of the C-rings on the properties of flavonoids and the corresponding semiquinones are revealed. Experimental methods including DLS and CD spectra indicated that with quercetin at room temperature did not induce aggregation of βlg, whilst binding with the other three flavonoids resulted in aggregation of βlg.

In recent years, single-atom catalysts (SACs) with separated active centers and high atom utilization have grown significantly as a significant area of catalytic research. In catalytic applications, SACs of various kinds have demonstrated exceptional performance, so the study of the catalytic mechanism of SACs provides a clearer direction for the preparation of catalysts with high performance. Strong linkages between the single atoms and the support are necessary to overcome the tendency of single atoms to aggregate into clusters, which is called metal-support interaction (MSI).

FcγRI plays a crucial role in the effector function of IgG antibodies, interacting with the lower hinge region of IgG1 with nanomolar affinity. Binding occurs specifically in domain 2 (D2) of the FcγRI ectodomain, while domain 3 (D3) is a flexible linker. The D3 domain is positioned away from the IgG binding site on the FcγRI and does not directly contact the Fc region.
